I am going out on Saturday and just found out that the HT-10s I got don't fit (just the rears). I am installing the HT-10s on the front only (I have no choice as anything here is mail order and would take at least a week).

This is my first time out on a square R-Comps setup after about 12 track days and a couple of HPDE schools.

Is there any concern with running the stocks in the rear? I have no choice so I will go out like that (except maybe getting new stock rears - worth it?). Anything to look out for? The rears have more than half of their life left.
